Because they both are fantastic Dystopian YA books, but they don't just have that in common, yes the plots are a bit different, but they both have kick ass female characters and the hot guy she loves. When I say kick ass I mean kick ass. It takes her a bit to be like that, but once she is I wouldn't want to be anyone in her way. You will be sucked in right away with both of these books, but Article 5 is based in Kentucky at the beginning and that's where I'm from so that's another thing I loved. I recognized so many places in this book! But yeah, you should try Article 5!

I would also compare Article 5 to a few other Dystopians such as The Giver and possibly The Fifth Wave (Without the aliens).
